ROLLER-SKATE SPECIFICATION forming part of Letters Patent No. 312,952,dated February 2 5-, 1885.

Application filed January 5 1885. (No model.)

To aZZ whom it may concern.-

- Be it known that I, Evnnirrr H. BARNEY, a citizen of the UnitedStates, residing at Springfield, in the county of Hampden and State ofMassachusetts, have invented new and useful Improvements inRoller-Skates, of which the following isa specification.

This invention relates to improvements in rollerskates, the object beingto provide improved axle'bearings in the journal-box and in the wheelsof such skates, whereby the frietion of the running parts thereof isgreatly reduced, and to provide an improved construction ofroller-journal box,whereby by permitting the skate-frame to set low,near to the axle, the height of the skate is less than those heretoforemadehaving similar bearings.

In the drawings forming part of this specification, Figure l is a sideelevation, partly in section, of the forward end of a roller-skateembodying my improvements. Fig. 2 is a longitudinal section of thejournal-box and wheels, showing the axle therein. Figs. 3 and 4.illustrate detail parts.

In the drawings, A is apart of the sole-plate of the skate, and B a partof the frame thereof. D is the journal-box, and -c is a spring securedto the frame and having one end bearing against the stud d on the lowerside of the 0 journal-box; and w is the axle, having the wheels 10secured thereon by the split washers 0c 00.

The construction and operation of the spring 0 with the frame A and thejournal-box, together with the manner of securing the wheels w on theaxle c by means of the split washers 6C, are all set forth in my patentsdated Octoher 3, 1882, and February 12, 1884:, to which reference maylie-had.

In my said patent of 1884 the journal-box post (I is shown perforated toprovide for oiling the axle through the post, as shown herein in Fig. 2of the drawings, but to make said post substantially a vacuumoil-reservoir, so that the oil therein will be delivered to the axle 12very slowly, and only so fast as demanded, and without waste, the postcl is provided'with the screw-plug e, which is screwed tightly into itafter the cavity in the post has been supplied with oil. \Vhen the skateis used, the oil will gradually escape from its reservoir, and followingthe axle will reach all of the parts upon which the latter bears,properly lubricating them. The ends of thejournal-box D adjoining theinner sides of the wheels w are provided with, rollersockets f, for thereception of aseries of parallel rollers, 2, their relative operativepositions being shown in Figs. 1 and 3. The said journalbox'is made ofmuch less diameter between the socket-cases j and the post (1 than isthat of said cases, in order to let the lower edge of the frame B of theskate set as near the axle o as possible, and thus reduce the height ofthe skate and the weight of the journal-box. Said rollers z surround theaxle o, the latter bearing upon the parallel surfaces of the roll ers,and the latter rolling in turn on the inner surface of the rimsurrounding said socket f when the axle turns. Said rollers are made ofsteel and hardenechand hence the axle rotates thereupon with very littlefriction. The rollers z are secured within the sockets f by the caps h,the latter and the sockets being provided with suitable ears, throughwhich pins 0, or screws, pass, fastening the caps to the sockets. Eachside of the wheel to is provided with a recess, w surrounding theaxle-hole through it, said recess being adapted to receive first theflat metallic disk 2'", and the metallic roller-cup z, the open side ofthe latter against said disk, the cup having ears thereon, through whichpins y, or screws, pass, reaching from side to side of the wheel, andsecuring the roller-cups firmly in the sides of the latter in thepositions shown in Fig. 2. The wheel to is made of wood to securelightness, and, obviously, may be used upon axles running injournal-boxes not provided with the rollers 2. hen the periphery of thewheels to becomes too muchworn for further use, the rollerfittings-thatis to say, the cups i, disks t", and rollers 0of each wheel may be transferred to a new wheel, and be further used until worn out. In the saidcup t in the wheel is placed a series of parallel rollers, 0, similar tosaid rollers 2, but shorter, so that in practice the aggregate length ofthe two series of rollers in one wheel equals about the length of one ofthe rollers in the socket in the end I00 of the journal-box, and Fig. 2shows. the arrangement of the rollers in both ends of the j ournal-box,the rollers in each side of the two wheels, and the latter secured onthe axle by the split washers or engaging in the grooves around theaxle. v

In the combined journal-box and wheel roller-bearing construction hereinshown and described provision is madefor the employment of a free axlewithin the journal-box bearings, and for free wheels havingrollerbearings therein to run on the free axle, and thereby the minimumamount of friction is encountered, and the skate runs with the greatestease.

What I claim as my invention- 1. In a roller-skate, the journal-box D,having a roller-socket at each end thereof, and provided with the postd, a series of parallel rollers arranged around the axle in said socket,and a cap covering the latter, in combination with the axle 12,substantially as set forth.

latter, in combination with the wheels w, each I of which has tworoller-cups secured thereto, having arranged therein around the axle twoseparate series of parallel rollers, substantially as set forth.

3. In combination, the journal-box D, having the perforated post d, thescrew-plug e, and the axle 12, substantially as set forth.

4. A journal for roller-skates,having a central passage for the axle,and provided with sockets in the ends thereof for the reception ofrollers and the post (1, and having those portions thereof between thepost and the adjoining sides of the socket-cases f of less diameter thanthelatter, substantially as set forth.

5. The wheel to, having on opposite sides thereof the recess 1020fgreat-er diameter than the axle-passage through it, the metallic disk1;, the roller-cup 1', having perforated ears on its border, and thescrews 3/, passing through the wheel and said ears, and the rollers 0,combined and operating substantially as set forth.

6. The wheel 40, having on opposite sides thereof the recess w",of,greater diameter than the axle-passage through it, the roller-cup i,having perforated ears on its border, andthe screws y, passing throughthe wheel and said ears, and the rollers 0, combinedaud operatingsubstantially as set forth.
